I have ubuntu 12.04, and 2 languages on my keyboard. Every time the screen goes black it requires my password, which is in English. But the language set is the one I have used last. How can I make it use English by default in the login screen? I am also ok with no password, it is my home computer.

Havent tried output but I think you can try with something like this:
search for the line:
Change it to:
Save and exit. Logout / Login or reboot the machine to apply the effect.
You can change the login keyboard preferences using System Settings, Region and Language, System tab:
Here you click Copy Settings. You should make sure that the current layout is english, otherwise you will stick with the previous layout. It will ask you for your password.
Once you have done this, log out and check if the settings are right.
